I super love this stuff!!! I recommended this to my brother and dad who have thinning hairlines and it seems to work pretty well for them too. My hair gets oily fast and goes flat but with this shampoo my hair stays thicker longer but still oh so soft. With this big bottle I only need to wash my hair about every three days so it lasts much longer.

I have been using this product for a while now, and I don't believe it makes my hair grow faster, but I do believe that it makes my hair feel more plump and full. The product lathers on very nicely, and I think it does a good job. The smell is not overbearing, but I think it could be a bit better.

I have thin, fine hair and was looking for something to give it a boost. This has a great smell and feels luxurious on pouring. It did make my hair feel a little more bouncy but I did find it made my hair feel course. This could be my own hair just not suitable for it. It is a higher priced shampoo but it is effective on the claims it made so for me overall it was good value ☺️

I love this shampoo I even have the conditioner. It does it's job for my hair. Even though I use heat tools I feel like my hair still looks healthy and smooth! My hair did grow which is why I'll continue to use this shampoo! It might have a strong sweet smell but then once you wash it off your hair smells bomb ! I've been using this product about 2 to 3 months now and my hair never felt more alive.

I love love love this shampoo. I can't even explain how much it has done for me. I suffer from thin falling off hair. I have tried expensive products and by far the comparison. I have seen a dramatic change in my hair. Now I have fuller and thicker hair. You just have to try it and see for yourself ❤❤❤❤❤

I use these every time I wash my hair. I have very fine hair. I used to have 5 or 6 different combinations of shampoo going in the shower at once and would use a different one depending on how my hair was acting that week. Since discovering this I haven't used anything else. My hair is fine and kind thin and since starting with this shampoo I have so much more volume and texture. Its a god send

I love this hair product. It's so easy to lather and a little goes a long way. The smell of the product lasts throughout the day. This product is definitely necessary if you have a dry scalp. Your hair will be full of healthy vitamins and oils once used and it won't disappoint. [product:ogx-biotin-&-collagen-shampoo]

The absolute best conditioner for thinning hair. OGX Biotin and Collagen Conditioner should be really expensive but it's not! I actually have beautiful body and gorgeous shine every time I use this. It won't weigh your hair down! Great for color treated hair because it's sulfate free!

Really nice shampoo. I use quite a bit of the OGX line of shampoos and conditioners, and I still have this one however I will say it's not my top pick. I think it would work really well with a different hair type but for me personally it left my hair feeling pretty soft but really frizzy. Still a good shampoo though and I would still recommend if you don't have extremely curly, moisture hungry hair.

I switch it up between the OGX keratin shampoo/conditioner and the OGX biotin and collagen shampoo/conditioner. I saw amazing results with my hair almost instantly that I've stuck with this brand and these products now for a few years and I would never go back to any other drug store brand.
